Conventional hair cosmetic materials have difficulty in achieving both high improvement effects on damaged hair and excellent sensation upon use. The present invention provides an oil-based hair cosmetic material to realize hair cosmetics having both high improvement effects on damaged hair and excellent sensation upon use, and a production method of the same.
The oil-based hair cosmetic material of the invention is those which comprise (A) a dibasic acid ester compound of general formula (1):
wherein R
1
is an alkylene group having a carbon number of 2-4, which may be mono- or poly-substituted, R
2
and R
3
are, independently of one another, an alkyl group having a carbon number of 1-4, which may be mono- or poly-substituted, R
4
and R
5
are, independently of one another, hydrogen or a methyl group or ethyl group which may be mono- or poly-substituted, m and n are, independently of one another, an integer of 0-4 with m+n≧1 (provided that the cases wherein R
2
and R
3
are both an ethyl group and m and n are both 1 are excluded), and (B) one or more oil agents selected from the group consisting of a volatile oil, an ester oil, a hydrocarbon oil, an animal/plant oil, and a silicone oil. Using this, it is possible to realize hair cosmetic materials and hair cosmetics that have both high improvement effects on damaged hair and excellent sensation upon use.
